Personality
She is somewhat of an airhead and has limited intelligence due to having low processing power, paying homage to the dumb blonde stereotype.

Astraea also harbors feelings for Sakurai Tomoki despite often being a target to his perversions. However, despite her lack of intelligence, she does display a good level of common sense in situations where Ikaros would be clueless about. Ironically, she is also regularly found starving due to the fact that she does not know how to hunt or obtain food by her own means, which was shown when she once buried herself to the ground because she tried to obtain nutrients the way plants did.

History
When she is ordered by Man of Synapse to eliminate Ikaros, she breaks off her chain and engages in combat with Chaos.

She makes her arrival on Earth in the woods outside of Sorami City right in front of Eishiro Sugata, who assumes that this new arrival from Synapse is nothing but trouble for Tomoki and sets off to locate him and warn him about this new threat.

Tomoki Sakurai
Tomoki is Astraea's unofficial master.

Man of Synapse
